Introduction to the structure and performance of blast furnace hot blast stove As the name implies, a hot blast stove is a thermal equipment that integrates combustion and heat transfer processes to provide hot air flow for the process. Generally, there are two major types, namely, the intermittent working regenerative hot blast stove and the continuous heat exchange hot blast stove. At present, when the high temperature ceramic heat exchange device is still immature, the intermittent working regenerative hot blast stove is still the mainstream product of the hot blast stove.Molybdenum and Molybdenum Alloy Vacuum Sintering Process In order to continuously provide hot air, the regenerative hot blast stove must have at least two hot blast stoves working alternately. Hot blast stoves are widely used in many fields of industrial production. Due to different process requirements, different fuel types, and different hot blast media, hot blast stoves with different uses and structures are derived. The hot blast stoves to be introduced here are the hot blast stoves that provide high temperature hot air for blast furnace smelting, and they are all regenerator hot blast stoves. Because of their intermittent working mode, multiple units must be cooperated to continuously provide high blast temperature to the blast furnace.Low temperature vacuum hot pressing sintering of aluminum nitride ceramics Classification of blast furnace hot blast stove The blast furnace hot blast stove can be divided into two categories: the hot blast stove with the external combustion structure and the hot blast stove with the internal combustion structure. In the hot blast stove with internal combustion structure, it is divided into top-fired type (the combustion chamber is placed on the upper part of the regenerator) and side-fired type (fire well combustion chamber and regenerator) due to the different relative positions between the combustion chamber and the regenerator.What needs to be done for heat treatment with vacuum oil quenching furnace?
