RX3 series 1200 ℃ high temperature box furnace is a national standard energy-saving box furnace. It is mainly used for alloy steel products, various molds for normalizing, quenching, annealing and other heat treatment, or diamond saw blades for high temperature sintering. A stainless steel nitrogen inlet pipe and valve are installed on the furnace side to adjust the intake air volume, which can play a simple role in protecting the atmosphere and reducing workpiece oxidation.
RX3 series 1200 ℃ high temperature box furnace shell is welded by steel plate and section steel. The furnace lining is built with ultra-lightweight energy-saving refractory bricks, combined with high-purity aluminum silicate fiber cotton insulation, and the electric heating elements are made of high temperature resistant alloy products 0Cr27Al7Mo2. It is placed on the wire bricks on the two walls of the furnace and the bottom of the furnace. There are two thermocouple holes on the top of the high-temperature box furnace. The thermocouple is inserted into the furnace when in use. The temperature and over-temperature protection of the box furnace are controlled by a temperature control system.
The high-temperature box furnace has automatic safety protection when it is opened and closed. There is a circuit breaker on the upper part of the furnace door. When the furnace door is opened, the power of the electric furnace is cut off. When heating is required, the furnace door is completely closed before the circuit breaker can be connected to start heating. , Reduce the use of box furnace failures. The heated workpiece is placed on the bottom of the silicon carbide furnace in the furnace. It is best to put a stainless steel plate on the bottom of the box furnace during use to prevent the workpiece from hitting the bottom of the furnace.
