Steam curing kiln and steam curing method

Abstract

The invention discloses a steam curing kiln and a steam curing method. The steam curing kiln comprises a kiln body, a steam control device, a water control device, a roller shutter door, a ventilationdevice and a master controller. A plurality of temperature sensors are arranged inside the kiln body. The steam control device comprises a steam inlet pipe, a first steam pipe and a second steam pipe. The first steam pipe and the second steam pipe communicate with the steam inlet pipe independently. The first steam pipe is provided with a plurality of first steam outlets. A first steam valve is arranged at the position of each first steam outlet. The second steam pipe is provided with a plurality of second steam outlets. A second steam valve is arranged at the position of each second steam outlet. The water control device comprises water spray pipes. Each water spray pipe is provided with a plurality of water spray ports. A water spray regulating valve is arranged at the position of eachwater spray port. The master controller is electrically connected with the ventilation device, the roller shutter door, the temperature sensors, the first steam valves, the second steam valves and thewater spray regulating valves respectively. With the steam curing kiln and the steam curing method, it can be implemented that temperatures of all points in the kiln can be accurately controlled, andthe quality and the production efficiency of track boards are improved.

Description

technical field [0001] The application relates to the technical field of track slab production, in particular to a steam curing kiln and a steam curing method. Background technique [0002] In the production process of the track slab, it is necessary to go through the key link of steam curing, that is, inject the concrete material into the track slab mold equipped with a steel frame, and after vibration, place the track slab mold in a steam curing kiln. Filled with high-pressure steam, the temperature in the kiln is adjusted by controlling the steam valve to speed up the solidification of the concrete, thereby shortening the production cycle of the track slab and ensuring the quality of the track slab. [0003] During the production process, the applicant found that the existing steam curing kiln cannot realize the precise control of the temperature in the kiln, and the local temperature is prone to be too high or too low, resulting in poor quality of the track plate after s...
