井式电炉料筐的改进装料筐是井式电炉不可缺少的附件，具有气流导向作用，有利于炉内气氛的对流，并使上、下炉温均匀，减少温差。但热处理过程中，零件在料筐内若堆集过密，将使炉内热气流循环阻力增大，影响炉内热流，造成炉温不均，零件热处理之后力学性能差异较大。因... Pit electric basket improvement loading basket is an indispensable well-type electric furnace accessories, with air-oriented role in favor of the convection of the atmosphere in the furnace, and the upper and lower furnace temperature uniformity and reduce the temperature difference. However, if the parts are densely packed in the baskets during the heat treatment, the circulation resistance of the hot gas flow in the furnace will increase, affecting the heat flow in the furnace, resulting in unequal furnace temperature. The mechanical properties of the parts after the heat treatment are greatly different. because...
