Utility model induction melting furnace for avoiding cracking of furnace bottom_Energy saving induction heating equipment manufacturers

Induction melting furnace is a melting furnace that uses the principle of electromagnetic induction to heat the metal placed in the inner cavity of its own furnace . The conventional induction melting furnace generally includes a furnace body component and a furnace bottom located at the lower part of the furnace body component. The furnace bottom is composed of multiple refractory bricks. During the process of smelting metal, the working conditions of the furnace bottom are generally very harsh. Withstand high temperatures above 1600 degrees Celsius, and the high temperature lasts for a long time. After the metal is smelted, this high temperature will drop sharply. When the next time the metal is smelted, the furnace bottom must repeat the high temperature and rapid temperature drop process. In other words, the temperature of the furnace bottom is suddenly cold and hot, which can easily cause the furnace bottom to crack.

The technical problem to be solved by the utility model is to provide an induction melting furnace that can reduce the maximum temperature to which the furnace bottom is subjected when smelting metal, and can slowly reduce the temperature of the furnace bottom after the metal is smelted, thereby avoiding cracking of the furnace bottom. . The technical solution of the utility model is to provide an induction melting furnace having the following structure : including a furnace body component and a furnace bottom located at the bottom of the furnace body component, wherein the furnace bottom is made of a refractory material as a whole, and the interior of the furnace bottom is provided with Cooling pipes for cooling water. After adopting the above structure, compared with the prior art, the utility model induction melting furnace has the following advantages: Unlike the prior art furnace bottom, which is composed of multiple refractory bricks, the furnace bottom of the utility model induction melting furnace is made of refractory materials. It is a whole, and the cooling bottom can be provided with cooling water pipes. Therefore, in the process of melting the metal in the induction melting furnace of the utility model , the user can reduce the furnace by passing circulating cooling water into the cooling pipes. The maximum temperature that the bottom is subjected to, and after the metal is smelted, this water-passing state is maintained. At this time, the temperature of the furnace bottom will slowly drop under the action of cooling water. After the furnace bottom is completely cooled, the water flow is stopped. In this way, the utility model induction melting furnace effectively avoids the sudden cold and heat caused by the temperature

Cracking.
