HARDOX400耐磨板的板面为何这么平整/

HARDOX400耐磨板在粗挤压机架中冷轧时,务必将悍达耐磨损铸钢件数次旋转,因而,铸钢件全部的四个面均受加工,并使原粘附在上面的或再次产生的空气氧化鉄庋从铸钢件表层上掉下来。以便改进轧入标准,在冷轧的表层上焊补有凸块或是刻槽。凸块和刻槽在所轧金属材料上导致的印痕,之后在亮面轧轮间冷轧能被再次轧平。

When Hardox400 wear-resistant plate is cold-rolled in the coarse extrusion stand, it is necessary to rotate the Hardox400 wear-resistant steel casting several times. Therefore, all four sides of the steel casting are processed, and the air oxidation which originally adhered to or produced again falls off the surface of the steel casting. In order to improve the rolling in standard, there are bumps or grooves on the surface of cold rolling. The marks caused by bumps and grooves on the rolled metal material can be flattened again after cold rolling between bright rolling wheels.

所HARDOX400耐磨板先根据布局在下辊中和辊中间的下板孔,然后根据中辊和上亲中间的孔隙度(上板孔)回到。因而,中辊负载比其他的2个辊都大。

The Hardox400 wear-resistant plate is first arranged in the lower plate hole in the middle of the lower roller and the upper roller according to the layout, and then returned to the upper plate according to the porosity (upper plate hole) in the middle of the middle roller and the upper roller. Therefore, the load of the middle roll is larger than that of the other two rolls.

恰当的板孔设计方案,即恰当的明确热轧带钢间孔隙度的规格,是圆满冷轧关键的前提条件之一。-般按所轧金属材料的强度开展板孔设计方案。对锻造软钢而言,常见25%的均值压下率开展测算。1300°时的冷轧工作压力应该比1200°时的小二分之一。在开坯机里,终轧溫度大概相当于900°。因而,以便保証一样的压下量,900°时的冷轧工作压力应该比1300°时的大3至4倍,由于在那样低的溫度下,金属复合材料的形变早已大大的上升。

Proper hole design, i.e. proper specification of porosity between hot rolled strips, is one of the key preconditions for successful cold rolling. -Generally according to the strength of rolled metal material to carry out plate hole design. For forged mild steel, it is common to calculate the average reduction rate of 25%. The working pressure of cold rolling at 1300 ° should be half less than that at 1200 ℃. In the blooming mill, the finishing temperature is about 900 ℃. Therefore, in order to ensure the same reduction, the cold rolling working pressure at 900 ° should be 3 to 4 times higher than that at 1300 ° because the deformation of metal composites has been greatly increased at that low temperature.

所轧金属材料从粗挤压机架进到用“张口”轧槽工作中的精挤压机架中;换句话说以便使轧材做到所期待的薄厚,孔隙度能够调整其尺寸,可将热轧带钢一个对一个地互相分离。厚钢板的薄厚在于薄方坯的薄厚,因而,挤压机的热轧带钢安裝的*度具备挺大的实际意义。假如薄方坯的薄厚超过容许程度,则不可以维持厚钢板的要求薄厚,由于耐磨钢冷轧常常依据制成品轧材的长短考虑。

In other words, in order to achieve the desired thickness and porosity, the size of the rolled strip can be adjusted, and the hot rolled strip can be separated from each other one by one. The thickness of the thick steel plate lies in the thickness of the thin billet. Therefore, the installation of the hot rolled strip in the extruder has great practical significance. If the thickness of the billet exceeds the allowable level, the required thickness of the heavy plate can not be maintained, because the cold rolling of wear-resistant steel is often considered according to the length of the rolled product.

在进行声卡机架前边,配有从薄方坯轧件上机械设备。

In front of the sound card frame, there is a mechanical equipment from the thin billet rolling.

这类机器设备有三把刮板,在其中俩把装在轧件下边,一把在上面。用气动式装K橾纵刮板并把刮板卡紧所轧金属材料。在三把刮板的功效下;以便加强这类全过程,则提供45-50大气压力的流水。还可以用蒸汽来替代水。

There are three scrapers in this kind of machinery and equipment, two of which are installed under the rolled piece and one on the top. Install the K-shaped longitudinal scraper pneumatically and clamp the scraper tightly to the rolled metal material. Under the effect of three scrapers, in order to strengthen the whole process, it provides 45-50 atmospheric pressure water. Steam can also be used instead of water.

当轧件离去研磨抛光机架之后进到配有隔板的切断机,而在切断机上把轧件裁成一定长短的悍达耐磨钢。薄方坯加工过程的每个工作先后开展。

When the rolled piece leaves the grinding and polishing frame, it goes to the cutting machine equipped with partition plate, and on the cutting machine, the rolled piece is cut into a certain length of hada wear-resistant steel. Each work in the process of thin billet processing is carried out successively.
