Embodiment Construction

[0037] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] According to the embodiment of the present invention, a method for stably controlling C in the kiln road clinker is provided. 3 A content approach, including:

[0039] a. When the material is closed, the mixing is reduced; the road clinker is cleaned and dried after cleaning to reduce the mud content; step a also includes:

[0040] Before the limestone enters the factory, the mud content of the limestone is controlled by inspecting CaO, SiO2 and silicon oxide according to on-site sampling inspection;

[0041] During the production of road clinker, the limestone shall be confirmed in each shift, and samples shall be taken for inspection and analysis;

[0042] Strengthen on-site monitoring, and inspect the i...

Abstract

The invention discloses a method for stably controlling the content of C3A in clinker in a road getting out of a kiln. The method comprises the following steps: reducing material mixing on a material flat bin; washing the clinker in the road, and drying after washing for reducing the mud content; additionally arranging a wind pipe on a material stirring site to ensure smooth discharging of materials and improve calcination quality; and adjusting the mixture ratio of the clinker in the road, wherein the clinker in the road comprises the following components in parts by weight: 2.5 parts of C3A, 50.20 parts of CaO, 1.27 parts of MgO, 13.1 parts of SiO2, 2.37 parts of Al2O3 and 3.35 parts of Fe2O3. According to the method for stably controlling the content of C3A in the clinker in the road getting out of the kiln, disclosed by the invention, the defects of large mud content, unstable quality, unreasonable mixture ratio and the like in the prior art can be overcome, and the advantages of large mud content, stable quality and reasonable mixture ratio are further realized.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for stably controlling C in kiln road clinker 3 A content method. Background technique [0002] C 3 A, that is, tricalcium aluminate, which is characterized by high heat of hydration and fast hydration reaction. If C in cement 3 If A is too high, it will cause the concrete to collapse too quickly when it is mixed into concrete, which will easily cause false coagulation. Seriously affect the durability of concrete. Road portland cement is mostly used in road construction, especially in the construction of some highways or airport runways, which have particularly strict requirements on concrete. Therefore, the road portland cement standard GB13693-2005 stipulates that C in road cement clinker 3 A content is less than or equal to 5%. And in terms of engineering, the stability of quality is very important. [0003] The 1# production line was built in 1958 and...
