A method of casting a thin strip is disclosed. The method includes assembling a pair of side dams adjacent end portions of counter-rotating casting rolls through which a strip of metal can be cast to permit a casting pool of molten metal to be formed supported by the casting surfaces of the casting rolls, assembling an angular actuator connected to a side dam at an angle urging the side dam toward the casting pool with a hold down force component urging the side dam downwardly, assembling a metal delivery system above the casting rolls delivering molten metal to form a casting pool supported on the casting surfaces of the casting rolls above the nip and confined by the pair of side dams, and counter-rotating the casting rolls such that the casting surfaces of the casting rolls each travel inwardly to produce a cast strip downwardly from the nip.

A method of forming a coating of an Al-Zn-Si-Mg alloy on a steel strip to form an Al-Zn-Mg-Si coated steel strip is disclosed. The method includes the steps of dipping steel strip into a bath of molten Al-Zn-Si-Mg alloy and forming a coating of the alloy on exposed surfaces of the steel strip and cooling the coated strip with cooling water. The cooling step includes controlling the pH of cooling water to be in a range of p H 5-9. Particular embodiments focus on Al-Zn-Si-Mg alloys that contain the following elements in % by weight: Zn: 30 to 60, Si: 0.3 to 3, Mg: 0.3 to 10, and Balance Al and unavoidable impurities.

摘要:
A method of continuously casting metal strip comprises delivering molten metal supported on the casting surfaces of the casting rolls and counter rotating the casting rolls to form metal shells on the casting surfaces brought together at the nip to deliver cast strip downwardly with a controlled amount of mushy material between the metal shells. The method also comprises determining at a reference location downstream from the nip a target temperature for the cast strip corresponding to a desired amount of mushy material between the metal shells of the cast strip and sensing the temperature of the cast strip cast downstream from the nip at the reference location and producing a sensor signal corresponding to the sensed temperature. The method also comprises causing an actuator to vary the gap at the nip between the casting rolls in response to the sensor signal received and processed to determine the temperature difference between the sensed temperature and the target temperature.

A thin cast steel strip and method of making thereof with improved resistance to microcracking is disclosed. The steel strip is produced by continuous casting and contains a carbon content between about 0.010% and about 0.065% by weight, less than 5.0% by weight chromium, at least 70 ppm of total oxygen and between 20 and 70 ppm of free oxygen, and manganese to sulfur ratio greater than about 250:1. The carbon content in the cast strip may be below 0.035%, less than 0.005% by weight titanium, and the average manganese to silicon ratio in the strip produced may be greater than 3.5:1. The carbon content may be less than 0.035%, the casting speed less than 76.68 meters per minute, and the tundish temperature of the molten metal is maintained below 1612°C (2933.7°F).

A method and an apparatus for producing a plurality of roll-formed cladding sheets for building a structure, such as a roof, are disclosed. The method includes optimal sequenced production of sheets from strip, with square cuts being made to the strip to form sheets, and then angle cutting of selected square cut sheets that comprise multiple smaller sheets nested together to form smaller sheets, with the smaller sheets having angle cuts at one or both ends of the sheets.
摘要:
A water storage tank is disclosed. The tank comprises an outer shell (2) that defines an interior of the tank, at least one water catchment bag (48) located in the tank interior, at least one inlet (19) in the outer shell for passage of water into the bag (s), and at least one outlet (21) in the outer shell for passage of water from the bag(s). A base for supporting a water storage tank is also disclosed. The base defines a pallet on which either the other components of the tank in assembled form or kit form can be transported from a manufacturing location to an end-use location.
