推钢加热炉厂家品牌企业 圣霖国际顾客至上

炉子寿命长。由于高温作用、机械磨损和腐蚀等因素的综合作用，炉子不可避免会有损坏，必须定期对炉子进行检修，应尽可能延长炉之的使用寿命，降低***费用。

劳动条件好。要求炉子的机械化及自动化程度高，操作条件好，安全卫生，对环境无污染。

The furnace has a long life. Due to the combined action of high temperature, mechanical wear and corrosion, the furnace will inevitably be damaged. It is necessary to overhaul the furnace regularly, so as to prolong the service life of the furnace and reduce the cost of repair.

The working conditi*** are good. It is required that the mechanization and automation of the furnace are high, the operating conditi*** are good, and the environment is safe and sanitary, and the environment is not polluted.

转底式加热炉

炉身固定，炉底转动，放置在炉底上的料坯随炉底转动由进料口移送到出料口。根据炉底的形状，转底式加热炉可分为环形炉和盘形炉两种，冶金厂轧钢车间多用环形炉。

Bottom reheating furnace

The furnace body is fixed and the bottom of the furnace is rotated, and the billet placed on the bottom of the furnace is transferred to the discharge port from the feed inlet with the rotation of the furnace bottom. According to the shape of the furnace bottom, the rotary hearth furnace can be divided into two types: the annular furnace and the disc type furnace.

对流传热：对流传热是炉气与钢材表面接触时的热交换过程，包括炉气各部分发生位移所产生的对流作用及炉气分子之间的导热作用。

Convective heat transfer: convection heat transfer is the heat exchange process of the contact between the furnace gas and the steel surface, including the convection of the displacement of each part of the furnace gas and the heat conduction between the molecules of the furnace gas.
