$how to increase the service life of refractories$

How to increase the service life of refractories?

How to increase the service life of refractories? Refractories are a kind of consumables for high temperature equipment. The use of refractory lining to resist high-temperature erosion can protect the facility from being damaged, but due to the selection of refractory materials and various factors, the use effect is not ideal. As a refractory manufacturer, today we will focus on how to increase the service life of refractory materials. Reasonable plan 1. Regarding different working conditions and different using positions for the industrial furnaces, different refractory materials. It’s the direct factor to increase the service life of refractory materials. 2. The structure of the furnace bodies should be designed reasonably. For example, the roof of the open hearth is changed…

cement kiln crusting and clogging causes and solutions

Cement kiln crusting and clogging causes and solutions

Cement Kiln Crusting And Clogging Causes And Solutions Cement kiln crusting, clogging and build-up of raw materials in the precalciner system are still common challenges in the cement production process. In precalciner kiln systems, when raw materials are heated, thermal and physical effects can lead to skinning and clogging of the raw materials in certain areas of the system, resulting in stagnant material flow. Fireramo, the refractory manufacturer, summarizes the main causes of crusting and clogging problems in cement kiln precalciner systems and the measures to solve them. Main causes of raw material skinning inside the cement kiln Uneven composition of raw materials The composition of raw materials used in the cement production process may be non-uniform. Raw materials with…
