摘要： The invention relates to free-machining steels which do not rely on lead as a means of enhancing machinability. Instead, the steels of the invention employ concentrations of tin, arsenic, and/or antimony at ferrite grain boundaries to replicate a role of lead, which the inventors have discovered, in enhancing machinability. This role is to cause an embrittlement at the localized cutting zone temperatures by changing the fracture mode from transgranular to intergranular at those temperatures. The invention's use of concentrations of tin, arsenic, and/or antimony at the ferrite grain boundaries of the steel permits the machinability-enhancing effect to be obtained while employing bulk contents of tin, arsenic, and/or antimony below the levels at which hot tearing becomes problematic. The invention improves over lead-bearing, free-machining steels in that the machinability-enhancing embrittlement produced by concentrating tin, arsenic, and/or antimony at the ferrite grain boundaries is both controllable and reversible. The invention also relates to methods of producing the described free-machining steels and the products of those processes.

摘要： A top hat furnace especially adapted for annealing steel sheet metal using a protective gas includes a protective top surrounding the batches of sheet steel metal. A cooling top is arranged above the protective top forming an intermediate space. The cooling top has a cover and a lid. The cover of the cooling top has a plurality of air nozzles so that cooling air impacts the protective top in the form of jets. At least one fan produces a flow of cooling air in the intermediate space. The distance between the air nozzles increases from the bottom of the cover towards it upper end. The distance between the nozzles is from four to twelve times greater than is the diameter of each nozzle. The cooling lid is also provided with a plurality of air nozzles. The distance between the nozzles in the cooling lid is from four to seven times greater than is the diameter of each of these nozzles.

摘要： Disclosed is an apparatus for effecting precise thermal cycling of articles by alternately employing electrical heating elements and circulating cooling water in conjunction with a controller to accurately regulate the temperature of a working surface. The apparatus includes a thermal tray in which articles are mounted in recesses formed in the working surface region thereof. The thermal tray is removable from the base of the apparatus which houses the heating elements and cooling water. Thus, thermal trays are interchangeable atop the base as desired. Also disclosed is a weight assembly for maintaining the articles in the recesses. This allows the thermal tray of the present invention to be transported to each of a plurality of processing stations, including the aforementioned thermal processing atop the base, while still maintaining precise positioning of the articles throughout each of the processes.
