自从采用连续浇铸工艺以来,人们一直在设法提高连续浇铸轧钢钢板的质量,其中包括浇铸工艺过程中铸模内钢水的最佳冷却问题及钢水恒定静压力问题。在一定范围内,维持铸模中一定的液位,是解决上述问题的条件之一。通常用浇口塞来调整钢水的流入量以控制结晶器中的液位。这里介绍一个控制系统。此系统和相应的机械设备配套应用,在轧制横截面约1500×180(毫米)的钢板,拉出速度为1.2米/分左右时,液位控制精度可达±5毫米。
Since the continuous casting process, there has been an ongoing effort to improve the quality of continuously cast steel sheets, including the optimum cooling of molten steel in the mold during casting and the constant static pressure of molten steel. In a certain range, to maintain a certain level of mold, is one of the conditions to solve the above problems. Gate plugs are often used to adjust the inflow of molten steel to control the level in the mold. Here’s a control system. The system and the corresponding mechanical equipment supporting the application, the rolling cross-section of about 1500 × 180 (mm) of steel, drawing speed of 1.2 m / min or so, the level control accuracy of ± 5 mm.
