Problems solved by technology

The high-temperature pellet material falls from a high place and impacts the inlet of the annular cooler, resulting in damage to the refractory material at the inlet of the annular cooler and burn-through of the equipment
The service life of the refractory material at the inlet of the annular cooler is short, generally 1-2, which not only has high cost of use, but also affects production

Abstract

The invention relates to a feed inlet of a circular cooler in the metallurgical industry, in particular to a material of the feed inlet of the circular cooler. The material of the feed inlet of the circular cooler is CrNi cast steel and comprises the following chemical components: 0.2-0.5% of C, 1-2% of Mn, 17-30% of Cr, 7-27% of Ni, not more than 2.0% of Si, not more than 0.5% of Mo(N), not morethan 0.04% of S, not more than 0.04% of P and the balance of Fe. The material adopts the heat-resistant cast steel, carries out protection on the part which is easy to be impacted and replaces a stamp mass, thereby greatly shortening the construction period; the material can not only bear the impact of high-temperature pellets, but also have the role of thermal insulation; the material can greatly prolong the service life of the heat-resistant material of the feed inlet, and the service life is 2-3 years generally; and the using cost is low.

Description

Technical field [0001] The invention relates to a material inlet of a ring cooler used in the metallurgical industry, in particular to the material of the material inlet of the ring cooler. Background technique [0002] The existing masonry of the inlet of the ring cooler adopts the type of refractory knotted material, which requires curing and baking and drying, and the construction period is long. The high-temperature pellets fall from a height and impact the inlet of the ring cooler, causing damage to the refractory material at the inlet of the ring cooler and burning through the equipment. The life of refractory material at the inlet of the ring cooler is short, generally 1-2, which not only has a high cost of use, but also affects production. Summary of the invention: [0003] In order to overcome the shortcomings of the prior art, the present invention provides an annular cooler inlet, which has short construction period, impact resistance, long service life and low use cos...
