Steel ladle anti-erosion aggregate preparation process and equipment thereof

Abstract

The invention relates to the technical field of aggregates, and discloses a steel ladle anti-erosion aggregate preparation process and equipment thereof. The equipment comprises an outer frame, a topcover is arranged at the top of the outer frame, a bottom frame is fixedly installed at the bottom of the outer frame, a hanging plate is arranged in the outer frame, a motor is arranged in the outerframe, and the output end of the motor is sleeved with a sleeve rod; a rotating rod is arranged at the bottom of the sleeve rod, the top of the rotating rod extends into the sleeve rod through the bottom of the sleeve rod, and stirring blades are fixedly mounted on the bottom wall surface of the rotating rod. According to the steel ladle anti-erosion aggregate preparation process and equipment thereof, part of pores and micro-cracks in adhesive mortar are filled, so that the aggregate becomes compact, the diffusion path of chloride ions in recycled concrete is prolonged to a certain extent, the anti-erosion purpose is achieved, the required equipment investment is small, new equipment does not need to be developed, equipment required for neutralization can meet the requirements by using concrete durability test equipment, the power energy consumption is low, and the effect of reducing the cost is achieved.

Description

technical field [0001] The invention relates to the technical field of aggregates, in particular to a preparation process and equipment for anti-corrosion aggregates for ladles. Background technique [0002] Aggregate is also called "aggregate". Granular material that acts as a skeleton and filling in concrete and mortar. There are two kinds of fine aggregate and coarse aggregate. The diameter of fine aggregate particles is between 0.16 and 5 mm. Natural sand is generally used, such as river sand, sea sand and valley sand, etc. When there is a lack of natural sand, artificial sand ground from hard rocks can also be used; the diameter of coarse aggregate particles is greater than 5 mm, and gravel and pebbles are commonly used. Under the same conditions, the strength of crushed stone concrete is higher than that of pebble concrete, but crushed stone is made of crushed rocks, and the cost is higher than that of pebbles. Coarse aggregates commonly used in lightweight aggrega...

AI Technical Summary

Problems solved by technology

Among them, the equipment investment required by the physical method is large, and the wear and power consumption are also large, which can promote the internal damage of the aggregate; the biological method is immature, and the test conditions are harsh and difficult to control; the solution impregnation in the chemical method Fado uses organic silane, organic polymer solution or some other waterproof materials, which are expensive; due to the low content of alkaline substances in the aggregate, the traditional method of carbonizing aggregate has no effect on the improvement of the chlorine salt erosion resistance of recycled concrete. Significantly; the acid solution immersion method is highly corrosive, has certain damage to the carbonate aggregate, and destroys the alkaline environment inside the recycled concrete; the grouting method is to mix single or multiple The slurry formed by this material wraps the aggregate, the process is simple and economical, but the improvement effect is limited
