A brick well is a hand-dug well with walls of brick, sometimes called "Dutch brick" if trapezoidal or site-made. The technique is old, but still applicable in developing countries where labor costs are low and materials are expensive.Ancient[edit]Wells dug by hand are mentioned in the Bible. [1] Mes
READ MOREThe manufacturing process of high alumina bricks is similar to that of clay bricks. But the difference is that the proportion of clinker used in high alumina bricks is relatively high, up to 90~95%. Before the clinker is crushed and fired at a high temperature of up to 1500~1600 degrees, all the iro
READ MOREThe crystallizer, secondary cooling zone, tension leveler, cutting equipment and other equipment of the horizontal continuous caster are installed at the horizontal position, and the tundish is closely connected with the crystallizer. A separation ring is installed at the connection between the tundish nozzle and the crystallizer. During billet drawing, the mold does not vibrate
READ MOREIn the early days, two high rolling mills were used to roll plates and strips. Because the rolling pressure is very large when rolling plate and strip, in order to ensure sufficient rigidity, the roll diameter is required to be large enough. However, with the increase of roll diameter, the elastic flattening of roll also increases, so the two high mill can only roll thick narrow strip.
READ MOREThe crystallizer of vertical and vertical bending continuous casters is straight, while the arc continuous caster adopts the arc crystallizer with a certain curvature radius. The crystallizer, secondary cooling device and tension straightening device are arranged on the quarter radian of a circle with a certain radius. The slab has been bent when solidified in the mold.
