What conditions are required for the production of heating furnaces
Heating furnaces are widely used in many metal parts manufacturing plants. Then, what are the requirements for the production of heating furnaces? The production of heating furnaces must not only have relevant qualifications, but also relevant technologies. There are previous prerequisites for different parts and grinding tools. Only materials can be used to manufacture the relevant heating furnace. In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats a material or workpiece (usually metal) to a rolling temperature. Kehua heating furnaces are used in many industries such as petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals. Production heating furnace Structural composition: According to the distribution of furnace temperature, the furnace chamber is divided into preheating section, heating section and soaking section along the length direction. The lower furnace temperature at the feed end is the preheating section, and its function is to use the heat of the furnace gas to improve the thermal efficiency of the furnace. The heating section is the main heating section, and the furnace gas temperature is relatively high to facilitate rapid heating. The soaking section is located at the discharge end, and the difference between the temperature of the furnace gas and the temperature of the metal material is small, ensuring that the section temperature of the discharged billet is uniform . Production Heating Furnace Working principle: Kehua's furnace for heating small cut fabric blanks only has a preheating section and a heating section. It is customary to divide the furnace section according to the heat supply zone where the burner is installed in the furnace, and the furnace is called one-stage type, two-stage type, five-stage type, six-stage type, etc. according to the number of supply zones. In the 1950s and 1960s, due to the increased capacity of the rolling mill, and the length of the pusher furnace was limited by the length of the pusher, the heating belt was added at the feed end, and the non-heating preheating section was cancelled to improve the Productivity per unit floor area. Using this furnace to heat slabs, the output per unit area of u200bu200bthe furnace bottom is 900-1000 kg/(m2·hour), and the heat consumption is about (0.5-0.65) × 106 kcal/ton. Since the 1970s, due to the need for energy saving, and because the emerging walking furnace allows to increase the length of the furnace, a non-heating preheating section has been added. time), the heat consumption is about (0.3 ~ 0.5) × 106 kcal/ton. Continuous heating furnaces usually use gas fuel, heavy oil or pulverized coal, and some burn lump coal. In order to effectively utilize the heat of exhaust gas, a heat exchanger for preheating air and gas, or a waste heat boiler is installed in the flue. Many manufacturers that produce heating furnaces basically customize the workpieces made by customers. After all, there are different steels and different workpiece shapes, so many molds are customized.
