Abstract

The invention discloses an antique green brick with Taihu silt as the main raw material, and the raw materials are Taihu silt, clay powder, waste float glass powder, coal powder, waste rubber powder, pig iron powder, steel slag particles and discarded green bricks ; Its preparation process is characterized in that the firing steps are as follows: the heating rate of the preheating section is 1 ~ 1.2 o C / min, it takes 13.5~20 hours to heat up; after the preheating section ends, it enters the high temperature firing section of the tunnel kiln, and the holding temperature of the firing section is 980~1090 oC , the flame atmosphere in the firing section is a weak oxidizing flame, and the holding time is 4 to 8 hours; o Within the temperature of C, the pressure of water vaporization to form saturated water vapor is controlled at 60‑120 Pa, and the cooling rate of this temperature range is 0.5~1.1 o C / min; temperature below 450 o C, enter the cooling section, the cooling medium in this stage is air, and the cooling rate is 0.5~1.2 o C / min. The average flexural strength of the antique blue brick prepared by the invention is 18-20 MPa, the average compressive strength is 20-24 MPa, and the impact resistance is 1.1-1.8 MPa.

Description

technical field [0001] The invention relates to an antique blue brick with Taihu Lake silt as the main raw material and a firing method thereof in a tunnel kiln, belonging to the technical field of antique blue bricks. Background technique [0002] The ancient buildings in our country have a long history and rich cultural connotations. The buildings featuring ancient blue tiles and blue bricks are even more unique, with their unique performance and aesthetic value. Green brick belongs to fired brick, which is a common building material. Because of its special production process and simple color, it is favored by people. The traditional sintering of blue tiles and blue bricks is generally sintered in small coal kilns or downdraft kilns. Small coal kilns are gradually eliminated due to heavy pollution, while downdraft kilns have the disadvantages of difficult operation, difficult temperature control, and low output. [0003] With the strengthening of environmental protection ...
