Current status of water sludge treatment at home and abroad

With the increasing amount of iron produced from the blast furnace, more and more slag is produced. It can be used as a good building material after proper treatment. For a long time blast furnace slag are done as waste to throw away, which is not only a huge waste, Li and slag pile up, encroachment of good land, impede traffic, and even limit the production of blast furnace.

Characteristics of refractory bricks

1, chemical composition: the main components determine the quality and characteristics of the refractory material 2, bulk density: weight per unit volume, density, indicating good densification, strength may be high, but the thermal conductivity may be large 3, apparent porosity: did not do specific requirements, but as a manufacturer must strictly control the apparent porosity.

The main use and technical requirements of water slag micro powder

Water slag is the product of placing blast furnace slag in hot molten state in water for rapid cooling, also known as blast furnace water quenching slag, is a by-product produced by blast furnace ironmaking, and is also known as mineral powder in the cement industry, and is mainly used in two ways: water quenching in slag ponds or water quenching in front of furnaces. Water slag is mainly used in the production of cement, which can be used as cement mix or made into clinker-free cement. Blast furnace water slag can be used as the main raw material for the production of slag micropowder after superfine grinding. It can be used as thermal insulation filler instead of silica bath soil, saving cost. It can be used to produce slag bricks and wet-milled slag concrete products. It is used as heat insulation filler.

Usefulness of water slag powder in mixing plant

The use of water slag powder in mixing plant refers to the use of water slag powder in concrete mixing plant, water slag powder is mainly used as a cementitious material in concrete, to enhance the concrete abrasion resistance, folding and seepage resistance.
