Problems solved by technology

[0003] Especially in the peak production season, in order to shorten the firing cycle, if the temperature distribution of the wide-body kiln is not adjusted in time, the horizontal left, middle, and The temperature difference on the right tends to increase continuously
As a result, the products arranged in the left, middle and right parts of the kiln are heated differently, and the difference in side length after leaving the kiln is getting larger and larger. The cutting amount of the post-trimming process needs to be adjusted frequently, which is time-consuming and laborious. Production Low efficiency, low pass rate

Embodiment

[0062] Before batch production of 600×600 ceramic tiles, check the temperature distribution uniformity of the cross-section perpendicular to the running direction of the ceramic tile kiln, and adjust the temperature distribution of the ceramic tile kiln to ensure the quality of ceramic tiles produced in batches The side length meets the quality control target of the range ≤ 1.0mm after firing. The specific steps are as follows:

[0063] 1. The width of the ceramic brick kiln to be tested is about 3.8m, and the heating channel is equidistantly divided into six areas of T1, T2, T3, T4, T5 and T6 with a width of about 0.633 meters along the running direction; select For six 600×600 ceramic tiles pressed in the same mold cavity, set the front sides of the six ceramic tiles in the direction of ejection as sides A1, A2, A3, A4, A5 and A6, and place the six ceramic tiles, etc. (the spacing is about 28mm) and placed in the T1, T2, T3, T4, T5 and T6 areas of the ceramic brick kiln, the...

Abstract

The invention discloses a method for detecting the temperature field uniformity of a ceramic brick kiln. The method comprises the following steps that S1) N ceramic green bricks which are pressed by the same mold and are in the same batch are taken, the N ceramic green bricks are arranged in the direction perpendicular to the running direction of the ceramic brick kiln to form the same straight line which stretches across the whole ceramic brick kiln and is perpendicular to the running direction; S2) the lengths from the A1 edge to the AN edge after firing are measured; and S3) an average value of the lengths from the A1 edge to the AN edge after firing is calculated, then an absolute value of a difference value between the length of each ceramic green brick after firing and the average value is calculated, the difference value is defined as a dimensional deviation value, and the N dimensional deviation values arranged in sequence according to the arrangement sequence of the ceramic green bricks during firing represent the temperature field uniformity of the ceramic brick kiln vertical to the running direction. The edge length of fired ceramic bricks is corrected through the detection method, the size of the fired ceramic bricks is controlled, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ceramic brick production, and in particular relates to a detection method for the temperature field uniformity of a ceramic brick kiln. Background technique [0002] With the development of the ceramic industry and the increase in demand, wide-bodied ceramic brick kilns are used more and more widely. In actual production, wide-body kilns inevitably have a cross-sectional temperature difference perpendicular to the operating direction. [0003] Especially in the peak production season, in order to shorten the firing cycle, if the temperature distribution of the wide-body kiln is not adjusted in time, the lateral temperature difference between the left, middle and right sides of the wide-body kiln is likely to increase continuously. As a result, the products arranged in the left, middle and right parts of the kiln are heated differently, and the difference in side length after leaving the kiln is getting la...
