Low-heat-conduction dip pipe and preparation method thereof
The invention provides a low-heat-conduction dip pipe and a preparation method thereof. The low-heat-conduction dip pipe comprises a steel liner, a pouring layer formed by pouring refractory material pouring materials is arranged outside the steel liner, refractory bricks are arranged inside the steel liner, a heat insulation plate is fixed to the outer wall of the part, used for being inserted into molten steel, of the lower portion of the steel liner, and the heat insulation plate is located in the pouring layer; a gap is formed between the inner wall of the steel liner and the refractory bricks, a low-heat-conduction pouring material is poured in the gap to form a low-heat-conduction pouring layer, and the low-heat-conduction pouring material is of a hollow structure. The heat insulation plate and the low-heat-conduction castable are adopted, so that the temperature of the steel liner is reduced, the thermal stress between the steel liner and the refractory material is reduced, and the service life of the dip pipe is prolonged.
本发明提供一种低导热浸渍管及其制备方法，包括钢胆，所述钢胆的外部具有耐火材料浇注料浇注形成的浇注层，内部具有耐火砖，所述钢胆下部用于插入钢液的部分的外壁固定有绝热板，所述绝热板位于所述浇注层内；所述钢胆内壁与所述耐火砖之间具有间隙，所述间隙内浇注低导热浇注料形成低导热浇注层，所述低导热浇注料中具有空心结构。本发明采用绝热板和低导热浇注料降低了钢胆的温度，减少了钢胆与耐火材料之间的热应力，从而提高了浸渍管使用寿命。
