Abstract
The present invention relates to a high chromium cast iron-high grade carbon steel bimetal compounding ball mill lining plate, which belongs to a new production process method of a bimetal compounding casting ball mill lining plate. The process method solves the problem that a large ball mill lining plate whose phi is more than 3M uses the optimal wear-resistant material-high chromium cast iron, and the lining plate simultaneously has high integral toughness and abradability. The present invention can be used for manufacturing a middle and large ball mill lining plate.
Description
The invention belongs to the manufacturing technique method of novel dual metal compound casting liner plate.
The ball grinding machine lining board of present domestic use mostly is not wear-resisting ZGMn13 material, and only to exceed one times or one times than the wearability of ZGMn13 more for Yan Zhi low-alloy steel liner such as 45Mn2 and 40CrMnSiMoRe in recent years.Generally acknowledged best high-abrasive material rich chromium cast iron can only be made the ball grinding machine lining board of diameter phi＜3M both at home and abroad.
The nearest domestic method that casting on flat rich chromium cast iron-45 bimetal copper-steel liner plate occurs, the double-metal layer became uneven occur easily dashing mixed cold shut defective, and castability depends on human factor.
The objective of the invention is to make liner plate to have high overall flexibility and wearability simultaneously, overcome the mixed phenomenon of dashing that casting on flat is prone to.
Pouring procedure of the present invention combines hard high-wearing feature and rich chromium cast iron with certain fragility and the quality carbon steel with excellent toughness, with the dividing plate of treated mild steel as two kinds of metals centres.So both guaranteed that two kinds of metals fused well, and guaranteed again can not dash to mix.Flat casting upright casting method need pour into die cavity simultaneously with two kinds of melt metal, and will guarantee that two kinds of metal bath surfaces slowly rise simultaneously.The molten steel molten iron of fusion raises baffle temperature rapidly in the dividing plate both sides, about dividing plate metal surface fusing 0.5mm.
The present invention requires central dividing plate to adopt the good mild-steel sheet of plasticity, and requires to remove the rusty scale and the dirt on surface, appears the metal surface, can form excellent metallurgical with the both sides metal and combine, and dividing plate also plays the effect of chill simultaneously, and it is fine and closely woven that foundry goods is organized.
The present invention requires to adopt the double teeming road to add the process of chill, and molten steel, molten iron are walked the running channel of oneself separately, and must not fling dividing plate.The adding of chill can reduce rising head even a cancellation rising head and a chilling action, guarantees the foundry goods densification.
Can not occur because partial condensation, cold shut phenomenon that oxidation occurred by pouring technology method poring rate speed of the present invention.
By pouring technology method of the present invention, because Design of Runner System is reasonable, liquid metal does not directly impact dividing plate, can not produce because of what the dividing plate fusing occurred and dash mixed phenomenon.
By pouring technology method of the present invention, because metal bath surface slowly rises, the binding site of bimetallic and dividing plate is not prone to bubble and nonmetal inclusion.
This is a kind of process of simple and reliable bimetallic composite casting liner plate.
Figure one is the adoptable two kinds of multi-form dividing plates of the present invention.
Figure two is casting system schematic diagrames.(1) be the upright casting road, (2) are cross gate, and (3) are carbon steel, and (4) are rich chromium cast iron, and (5) are central dividing plate.
Claims (2)
1, a kind of process of casting double metals compound ball mill lining palte, system's rich chromium cast iron-quality carbon steel casting one-shot forming, it is characterized in that, use treated mild-steel sheet as the central dividing plate between rich chromium cast iron and the quality carbon steel, with the cast of flat casting upright casting method, the double teeming road is used in cast, and the running channel that molten steel, molten iron are walked separately pours into die cavity simultaneously, and the liquid level of two kinds of metals slowly rises simultaneously.
2, process according to claim 1 is characterized in that central dividing plate removes surperficial rusty scale, appears the metal surface.
