Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with the examples.

[0023] The artificial bluestone consists of bluestone sand 40-50%, refining slag powder 30-40%, Portland cement 15-20%, magnetite powder 1-3%, high-efficiency water reducing agent 1-3%, titanium green 0.1% -0.3% composition, of which:

[0024] Portland cement: The main mineral composition is: tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite. Tricalcium silicate determines the strength of Portland cement within four weeks; dicalcium silicate exerts its strength after four weeks, and reaches the strength of tricalcium silicate in about one year; the strength of tricalcium aluminate It develops faster, and it plays a certain role in the strength of Portland cement within 1 to 3 days or a little longer; the strength of tetracalcium aluminoferrite also develops faster, and the characteristics of Portland cem...

Abstract

The invention discloses a method for preparing artificial bluestone from refined manganese slag and an artificial bluestone forming production line, and belongs to the field of metallurgy. The artificial bluestone is composed of 40-50% of bluestone sand, 30-40% of refined slag powder, 15-20% of Portland cement, 1-3% of magnetite powder, 1-3% of superplasticizer and 0.1-0.3% of titanium blue green.The artificial bluestone is treated according to the following steps: burdening and mixing, injection molding, curing and demolding to obtain a finished product. According to the method, the existingrefined manganese slag can be fully utilized, the problem that the refined manganese slag occupies a site due to long-term stacking and the environmental load caused by the refined manganese slag aresolved, a novel building material is provided for the field of buildings, and the appearance style of the buildings and the variety of the building materials are enriched.

Description

technical field [0001] The invention relates to a method for preparing artificial bluestone and a molding production line, in particular to a method for preparing artificial bluestone by using refined manganese slag and a molding production line for artificial bluestone, belonging to the field of metallurgy. Background technique [0002] Medium and low carbon ferromanganese is the key basic material in metallurgy, aerospace, chemical industry and other departments. While the world's medium and low-carbon ferromanganese industry is developing rapidly, it is also facing huge resource and environmental pressures, especially the disposal of refined manganese slag has become one of the concerns of the business community, academia and society. Since the refined manganese slag is acidic, has high moisture content, fine particles, and contains a large amount of ammonium ions and heavy metal ions, it is easy to pollute the environment if it is piled up in the open air for a long time...
