Disadvantages of modern tube furnaces

Disadvantages of modern tube furnaces (1) The strength of the furnace lining is low, and it is easily damaged by mechanical force during use;Production Management of Vacuum Quenching Furnace (2) The ability to resist airflow erosion is poor; (3) The construction environment is harsh and the quality is unstable due to the influence of human factors, so it is difficult to ensure the effect of the equipment in operation and use.Chain link vacuum quenching and tempering Castable structure The castable structure is mainly a furnace lining built with refractory materials such as heat-resistant concrete and castables. Its main advantages are good integrity and air tightness of the furnace lining, long life of the furnace lining, easy realization of mechanized construction operations, and high construction efficiency. The disadvantage is that the refractory material must be used within the validity period, and the lining repair is not as flexible as the brick lining.PCB micro-drill vacuum brazing
