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 an embodiment of the present invention, a method for stably controlling C3A content in kiln-exiting road clinker is provided, 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 incoming ir...

Abstract

The invention discloses a stable control method of a C3A content in drawn road clinker. The stable control method comprises the steps of reducing a mixed material on a flat material warehouse, cleaning road clinker, then drying to reduce a silt content, additionally arranging an air pipe on a poking site to ensure smooth material blanking and improve roasting quality, and adjusting a matching ratio of ingredients of the road clinker to be as follows (in parts by weight): 2.6 parts of C3A, 50.26 parts of CaO, 1.24 parts of MgO, 12.21 parts of SiO2, 2.34 parts of Al2O3, and 3.23 parts of Fe2O3. The stable control method of the C3A content in the drawn road clinker can overcome defects such as a high silt content, unstable quality and the unreasonable matching ratio in the prior art to achieve the advantages of low silt content, stable quality and reasonable matching ratio.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for stably controlling the content of C3A in kiln-exiting road clinker. 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 195...
