What are the maintenance techniques for high-temperature electric furnaces

Regularly check whether the connections between the electric furnace and the controller are outstanding. It is necessary to operate electric furnaces and controllers in places with a relative humidity not exceeding 85%, free from conductive dust, explosive gases, and corrosive gases that can damage metal insulation and electronic components. The operating environment temperature of the controller is limited to 0-50 ℃. When using electric furnaces and controllers, additional power should not be exceeded, and the furnace temperature should not exceed the additional operating temperature. It is prohibited to load wet workpieces into the furnace. Heated workpieces containing ultra-high moisture should be pre dried, and the furnace bottom should be carefully cleaned. Metal oxides, slag, and impurities inside the furnace should be promptly removed. When loading and unloading workpieces, caution should be exercised to prevent damage to the silicon carbide rod. The silicon carbide rod should be placed in a dry place to prevent the aluminum head from becoming damp and molting. If some rods are found to be incandescent while others are dark red during use, it should be clarified that the resistance changes of each rod are different. It is necessary to replace them with rods with similar resistance values before starting from scratch. Silicon carbide rod is a recrystallized product of silicon carbide, which can be corroded by alkali, alkali metal, sulfuric acid, and boron compounds at high temperatures.

Knowledge related to aging furnaces

The aging furnace is used for tempering workpieces and parts, as well as quenching and aging of aluminum alloy parts. Its function is similar to that of a quenching furnace, and it also belongs to the cycle running electric furnace.

Brazing furnace equipment requires frequent maintenance

Before applying large and medium-sized brazing furnace equipment, everyone must carefully read the operating instructions inside the aluminum brazing furnace in advance, and do not blindly follow the wind for actual operation, otherwise some small common faults will inevitably occur. So, what should we do?

Working principle of vacuum brazing furnace equipment

Vacuum brazing furnace is a mechanical equipment that uses copper welding wire to heat and melt to complete welding. Do you know the working principle of vacuum brazing furnace? Today, let's learn about the vacuum brazing furnace with Bian Xiao!

How to improve the heat utilization rate of brazing furnace?

In the process of using a brazing furnace, we all hope that the higher the efficiency, the better. So what can we do to improve its heat utilization rate? It's actually very simple. As long as we reduce heat dissipation, reduce heat storage in the furnace lining, and reduce the weight of fixtures and pallets, when we choose a furnace, we should also learn to recognize its quality. In this article, a detailed introduction will be provided around improving the heat utilization rate of welding furnaces and testing their quality techniques.

Raw materials and raw material tests required in the agreement on purchase of aluminum brazing furnace, attitude test of full flow spray equipment.

The main types and operating steps of brazing furnaces

Brazing furnace is a kind of equipment used for metal brazing and bright heat treatment, which is suitable for batch production of small and medium-sized stainless steel parts (tableware, tools, hardware, etc.), such as bright quenching and tempering of martensite stainless steel and bright annealing of austenitic stainless steel.

What to do if there is air leakage in the vacuum brazing furnace?

The vacuum instrument of the vacuum brazing furnace is within the valid range of use. After the leak detector detects a leak, the protective valve at the vacuum gauge pipe has a problem of air leakage, and the valve should be replaced.
