该系列工件预热保温炉外框架均采用型钢和钢板制造。炉内胆材质均为耐热不锈钢板制造（特殊要求采用铸铝内胆），外覆板与炉胆之间填优质硅酸铝棉隔热保温，箱式和卧式炉根据要求配有热风循环风机，通过风机将电热管产生的热量均匀吹送到炉膛内的被加热工件上对工件进行加热，使炉膛内形成一个温度均匀的热循环系统。

特殊要求可代为设计制造。

系列工件预热保温炉广泛适用于涤纶、锦纶、丙纶等化纤行业的各种纺丝工件、过滤器及热熔性塑料挤出成型设备上的模头、机件的预热保温，也适用于科研单位和实验室的干燥、烘焙、热处理之用。该设备具有升温速度快、温度均匀性好，控温精度高，操作方便等优点。

The stove is widely used for the warm-up and heat-presevation of spinneret, filter, die head and work of the plastic extrusion machine. It also adapted to the laboratory drying, baking and heat treatment.

The stove has many outstanding featuree: instant warm-up, precise temperature control, convenient operation etc. The outline border is made of profiled bar and armor plate, and the inside is made of refractory armor plate(casting aluminium for sepical demand). High quality silicic acid aluminium cotton has been filled between the outer shell and workroom for heat preservation.

The box-style stove and horizontal stove have a hot-air circle fan. And the heat power will be equably blew into Design and manufacturing services are available for special demands, too.
