The grate bar is the main part of the sintering machine trolley. The role of the grate bar is to form a trough-shaped space with the trolley rail to accommodate and carry mineral materials. The part where the grate is in contact with the ore is the upper surface. The two ends of the upper part of the grate are stressed and play a supporting role. The bottom of the grate has two functions. First, the role of the grate is fixed when the discharge is reversed Can not fall off; secondly, it plays a supporting role when the top of the grate is compressed, which can effectively prevent the grate from bending.
Production process as follow:
We are supplying many different kind of heat resistant steel castings to our customers and we use both investment casting process and sand casting process for different size or different structure casting. For suitable castings, we also choose lost foam process which have better cost and quality performance.
There have lot of different specifications for such castings, usually we produce according to customers drawings and specific requirement, following are the common materials which we usually supply:
| Typical material grade | ZG35Cr24Ni7SiNRe, ZG40Cr25Ni20Si2, 1Cr18Ni9, ZGCr25Ni35Nb, ZGCr28Ni48W5 HK40, HT, HU, HH, 22H, 304, super 22H, HP-Nb, More1, More2, 1.4848, 1.4855, 1.4852, 2.4879, 1.4460, 1.4462, S32205, S32750, etc. |
Our products are been widely use in cement plants, electric generate plant, melting industry, and other industries. In recent years, there are more and more professional municipal waste incineration stations, and we have developed a lot of heat-resistant casting products specially supplied to such factories.
