Tube furnace heating elements chosen silicon molybdenum rod (distributed around the hearth). MoSi2 heating element is a kind of molybdenum silicide-based resistance heating elements. Sintered molybdenum silicide products in an oxidizing atmosphere is heated to a high temperature, its surface layer of dense silica glass film box-type laboratory furnace manufacturers, it can not maintain the oxidation products. Therefore, silicon molybdenum rod element has a unique high temperature oxidation resistance. The maximum temperature in an oxidizing atmosphere to 1750 ℃. Resistivity silicon molybdenum rod element does not change with change (resistance increases with increasing temperature), which is not aging, so the old and new components can be mixed using the length of time. Silicon molybdenum rod system mechanical components and other ceramic products like brittle materials at room temperature are easy to break, but the use of appropriate and reasonable installation can be avoided. Box resistance furnace shape like a rectangular box. Box resistance furnace internal structure Picture 1 a door; 2 a heating element; a furnace shell 3; 4 a control box; 5- lining the main control box from the furnace and two major components. Box resistance furnace general working conditions in the natural atmosphere of the 1600 box-type resistance furnace, mostly working in the heating mode box-type laboratory furnace prices, the use of refractory lining and insulation materials do. Workpiece for normalizing, annealing, quenching and heat treatment and other heating purposes. According to different heating temperatures are generally divided into three types of box-type laboratory furnace, the temperature is higher than 1000 ℃ called high-temperature box resistance furnace at temperatures between 600 and 1000 ℃ called a box-type resistance furnace temperature, the temperature is below 600 ℃ called low-temperature box resistance furnace, in order to meet the needs of different heat treatment temperature.
