捷克Nov Hut公司的Conroll薄板坯连铸机引进了一种新型薄结晶器装置,它需要使用设计独特但结构复杂的浸入式水口耐火砖套。该连铸机的规格是:设备类型为VAI Conrolll25;结晶器尺寸为125mm×(740mm～1575mm);最高铸坯速度为2. 6m/min;钢的成分为C 0.07%～0.10%。Mn0.45%～0.50%,Si 0.03%～0.25%。英国Foseco公司开发了一种双水口耐火砖套,这种砖套具有复杂的几何形状,起顶部是直径为62mm的腔体,越往下越细,最终形成非几何对称的116mm×28mm的腔体。这种设计 The Conroll thin slab caster from Nov Hut, Czech Republic, introduces a new thin crystallizer that requires the use of submerged nozzle refractory bricks with a unique design but a complex structure. The continuous casting machine specifications are: equipment type VAI Conrolll25; mold size of 125mm × (740mm ~ 1575mm); maximum casting speed of 2. 6m / min; steel composition C 0.07% ~ 0.10%. Mn 0.45% -0.50%, Si 0.03% -0.25%. Foseco UK has developed a double-nozzle refractory brick cover that has a complex geometry, starting from the top of the cavity diameter of 62mm, the finer down, the final formation of a non-geometric symmetrical 116mm × 28mm cavity .
