摘要： Typically, pre-painted steel strip has been produced in a steel finishing mill by applying it as a solvent-free melted liquid to a hot steel strip substrate, known as melt deposition. Melt deposition rate has been effected by controlling the contact pressure between the solid paint and the hot steel strip substrate, while maintaining constant all the other parameters affecting the deposition rate. The difficulty of accurately controlling all of these parameters has in turn made it difficult to obtain a consistently low and constant deposition rate in the production of thin paint coats of uniform thickness. This problem has been overcome by feeding a solid body of paint onto an endless belt conveyor (9), incorporating a substantially planar belt flight (11), a head pulley (12) and turn round means adjacent to the contact point of the paint block (15) and the moving steel strip (5) and consisting of a stationary guide (13) and an idler pulley (14). The turn round means is so constructed that the direction of the belt movement after the turn is at least parallel to that of the continuously moving strip (5) and preferably at an angle away from it. The head pulley (12) is preferably coated with a high friction material such as natural rubber. The planar belt flight (11) is adapted to support a file of at least one and preferably two blocks (15) of solvent-free paint composition, which becomes bonded to the pliable, durable heat-resistant material of the belt. In its simplest form, the flight (11) may slide upon a supporting table with the stationary guide of the turn round being the edge of the table. Alternatively, the paint blocks (15) may be fed vertically downwards between two belt conveyors moving in mutually opposite directions.

摘要： A method of forming a coating of a polymer-based paint composition on a substrate (1) is disclosed. The method is based on the use of pellets (13) rather than solid blocks of the paint composition. The method includes pre-heating a substrate (1) to a temperature that is above the glass transition temperature of the polymer of the paint composition and supplying pellets (13) of the paint composition to the surface of the substrate (1) whereby the pellets (13) progressively melt into a liquid state. Thereafter, the method includes forming a coating of the liquid paint composition on the substrate surface (1) and converting the liquid coating into a solid coating of the paint composition.

摘要： In twin roll casting of steel strip, molten steel is introduced into the nip between parallel casting rolls (16) to create casting pool (30) supported on casting surfaces (16A) of the rolls and the rolls are rotated to deliver solidified strip (20) downwardly from the nip. Casting surfaces (16A) are textured by a random pattern of discrete projections having pointed peaks with a surface distribution of between 10 and 100 peaks per mm and an average height of at least 10 microns. The random texture may be produced by grit blasting the casting surfaces on a substrate covered by a protective coating. Alternatively the texture may be produced by chemical deposition or electrodeposition of a coating onto a substrate to form the casting surfaces.

摘要： A flow diversion device for use in a gas jet stripping apparatus includes a baffle (26) having a first portion (17) which in use extends longitudinally of the moving strip (4) which is being subjected to the stripping action of the jet stripping nozzles of the gas jet stripping apparatus. The baffle further includes a second portion (19) which diverges away from the moving strip (4) and a gas outlet (27) for providing gas to the strip side of the baffle (26). The baffle is characterised by a gas collection means (20) for redirecting gas from the stripping nozzles to the gas outlet (27). An auxiliary gas supply may be provided to supplement the gas exiting gas outlet (27) to ensure the correct operation of the flow diversion device.

摘要： In twin roll casting of steel strip, molten steel is introduced into the nip 16B between parallel casting rolls (16) to create casting pool (30) supported on casting surfaces (16A) of the rolls and the rolls are rotated to deliver solidified strip (20) downwardly from the nip. Casting surfaces (16A) are textured by a random pattern of discrete projections having pointed peaks and the strip is moved away from the casting pool at a speed of more than 60 meters per minute. In order to suppress chatter defects, the molten steel has a manganese content of less than 0.6% by weight and a silicon content in the range of 0.1 to 0.35% by weight. The random texture may be produced by grit blasting the casting surfaces on a substrate covered by a protective coating. Alternatively the texture may be produced by chemical deposition or electrodeposition of a coating onto a substrate to form the casting surfaces.

摘要： Twin roll casting has been applied with some success to non-ferrous metals, which solidify rapidly on cooling. The same, however, is not true for ferrous metals, as it has not been possible to achieve sufficiently rapid and even cooling of metal over the casting surfaces of the rolls. This problem has been overcome by utilising a metallic surface for the rolls, which has a high affinity for the molten steel of the casting pool and a melting temperature greater than the temperature of the casting surface. The molten steel produces extremely good wetting of the casting surface of the roll, resulting in a wetting angle of the molten steel on the casting surface of less than 40 DEG . Preferably, this wetting angle is less than 20 DEG and the casting surface has an Arithmetic Mean Roughness Value (Ra) of less than 10 microns. These desirable properties on the roll surface are achieved by selecting an at least partially amorphous alloy of two constituents. Preferably, the alloy is a fully amorphous alloy of the nickel-phosphorus systemcontaining about 10 % phosphorus and the balance nickel, which may be applied by eletroless coating. This roll surface prevents the build-up of iron oxide on the casting surfaces of the rolls, which build-up interferes with the uniform conduction of heat away from the molten steel, resulting in simultaneous solidification of the delta and gamma iron phases (0.01-0.18 %C), which causes a surface defect, known as "crocodile-skin". The net effect of utilising this amorphous alloy for the surface of the casting roll is a superior and uniform conduction of heat away from the molten steel, rapid transformation of the steel's microstructure into the wholly austenitic ( gamma ) region, exhibited by fine prior austenite grain boundaries conforming to dendritic grain boundaries and absence of "crocodile-skin" surface defects on the cast strip.
摘要翻译： 双辊铸造已经在有色金属上取得了一些成功，冷却时迅速凝固。 然而，黑色金属不是这样，因为不可能在辊的铸造表面上实现足够快速且均匀地冷却金属。 通过利用对浇铸池的钢水具有高亲和力并且熔融温度大于铸造表面的温度的轧辊的金属表面已经克服了这个问题。 钢水对辊的铸造表面产生非常好的润湿，导致铸钢表面的钢水的润湿角小于40°。 优选地，该润湿角度小于20°，并且铸造表面具有小于10微米的算术平均粗糙度值（Ra）。 通过选择两种成分的至少部分非晶合金来实现辊表面上的这些期望的性能。 优选地，该合金是含有约10％磷的镍 - 磷体系和其余镍的完全非晶合金，其可通过无电镀涂覆施加。 该辊表面防止在辊的铸造表面上堆积氧化铁，这种积聚会干扰来自钢水的均匀热传导，导致δ和γ相（0.01- 0.18％C），这导致表面缺陷，被称为“鳄鱼皮”。 利用这种非晶态合金在铸辊表面的净效应是远离钢水的优良且均匀的热传导，钢的微结构快速转变为完全奥氏体（γ）区域，由先前的奥氏体晶粒 符合树枝状晶界的边界和铸钢带上没有“鳄鱼皮”表面缺陷。
