The temperature and humidity at the inlet of the turks head rolling mill may affect its production efficiency. In order to strengthen the billet to achieve deformation rolling quickly, the inlet temperature of the small rolling mill should be kept within the allowable temperature range of the billet, and the temperature is 1,150 degrees.

The purpose of heating the billet is to achieve the thermal properties required for rolling it. It should be noted that physical and chemical changes such as discoloration, decomposition, melting and deformation of the billet are avoided. For the same type of billet, it is allowed to enter the same hole type, and the temperature varies with the heating furnace. For the same billet, different quenching heating temperature and holding time will also affect.

Generally, in a regenerative heating furnace, Turks head rolling mill,since the billet is stepped from the low temperature area to the high temperature area through the pusher, the temperature of the tapping port is high, and the billet is heated from both sides, and the billet does not need to be heated. Flip, can make the billet heating evenly, fast, short time.

The tapping port of the heating furnace of the small rolling mill has strict requirements on the humidity. In the case of no tapping, closing the furnace door can reduce the air consumption and heat transfer, which can reduce the cost of burning coal or gas. If the surrounding humidity is relatively high, the partial pressure of water vapor in the heating furnace of the rolling mill will increase, which will reduce the average driving force in the furnace. In order to maintain the same heating capacity, it is necessary to increase the length and width of the heating furnace at this time, which will increase the investment cost. .

When the steel is rolled and billeted, corners and surface cracks appear, which seriously affects the surface quality of the billet. Turks head rolling mill,For the same billet, the type of heating furnace selected is also different, and the appropriate relative humidity values are also different. If the temperature of the heating furnace increases, the heat loss will be large. If the temperature decreases and the relative humidity is high, the moist air may precipitate water droplets in the equipment and pipelines behind the ingot heating furnace, thus destroying the normal operation of the heating furnace. use.

The temperature change inside the billet when it is heated in the heating furnace is an important parameter, but currently only the surface temperature of the billet can be measured, and the internal temperature of the billet cannot be measured. The outlet temperature of the billet is in the heating furnace with continuous countercurrent operation. Air and gas enter the heating furnace together for combustion to evaporate the moisture in the billet, which is convenient for heating the billet to gradually increase its temperature.
