Embodiment Construction

[0036] The existing rotary kiln mouth pouring material construction method usually adopts a sequential construction method, and the kiln mouth pouring material is poured at one time. This construction method is likely to cause problems such as uneven expansion joints, pouring material falling off, damage to the kiln mouth, and low construction efficiency. , in order to solve the above problems, the present invention provides a construction method of pouring material for cement rotary kiln kiln mouth, the method divides a plurality of pouring blocks according to the number of protective iron blocks at the kiln mouth of the rotary kiln, and the pouring blocks are constructed at intervals, which is convenient for the construction process The setting of the middle expansion joint can ensure that the expansion joint is set evenly, and there will be no large-scale damage or falling off of the castable.

Abstract

The invention provides a construction method of a cement rotary kiln kilneye castable, and belongs to the technical field of cement production line construction. The construction method of the cementrotary kiln kilneye castable divides a plurality of casting blocks according to the number of back iron blocks at the rotary kiln kilneye, the casting blocks are marked with two different numbers, andthe casting blocks with the two numbers are arranged at intervals, and the construction of the cement rotary kiln kilneye castable is completed in a twice alternate pouring mode. According to the construction method of the cement rotary kiln kilneye castable, expansion joints are convenient to arrange in the construction process through twice alternate construction, it is guaranteed that the expansion joints can be uniformly arranged, and the phenomenon of large-area damage or falling off of the castable cannot occur; in the construction process of the twice alternate construction, side panels are not required to be arranged on two sides of the casting blocks, so that construction materials are saved, the operation is simplified, and the working efficiency is improved; and in the construction process, no plate is additionally arranged at the top, the working space of a vibrating spear is ensured, the castable is vibrated evenly, the gas in the castable can be discharged, the construction quality of the castable is ensured, and the service life of a casting part of the kilneye is prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction of cement production lines, and in particular relates to a construction method of castables for cement rotary kilns. Background technique [0002] The rotary kiln is the heart of the new dry process cement production line. The castable at the kiln mouth of the rotary kiln is more easily damaged than other parts of the cement kiln. The cement clinker is in the firing zone stage, where the cement clinker turns into particles in the liquid phase, which is highly abrasive, and the kiln mouth is at the front of the coal injection pipe. The high temperature makes the working environment of the kiln mouth refractory relatively bad. Therefore, the service life of the kiln mouth castable greatly affects the operation rate of the cement kiln. [0003] The traditional construction method of rotary kiln mouth castables is usually constructed sequentially during the process of rotating the rotary kiln, a...
