自动演奏钢琴价格:大家好，请帮我把关于步进梁加热炉的英文翻译成汉语！谢谢！

The movable supports are then lowered to deposit the work-pieces on the stationary members for support thereby. The movable supports are then retracted while spaced below the bottom surface of the workpieces to a starting position for a succeeding cycle to lift and advance the workpieces. Usually, two or more lifting beam assemblies extend in the direction of the length of the furnace chamber along the lateral sides of the stationary support to collectively form the walking beam assemblies. Heat insulating material, such as refractory, is usually provided in the furnace on the various surfaces along the hearth that contact and support the workpieces during movement within the furnace chamber. Such material is used to at least minimize, if not eliminate, the development of cold spots in the workpieces at the points of contact with the supporting surface of the walking beam assemblies. The heat insulating material, usually comprised of hightemperature refractory, must include a support having coolant facilities to restrain movement and prevent overheating.
walking beam assemblies(步进梁装置）,即使您用再线翻译也要仔细修啊！！不要很滥啊，在下写论文啊！！
