Application case 5

Application case 5: Carbon electrode baking control system

一. Carbon electrode baking control system

1. Overview

Carbon electrode roaster combustion device and control system for 38 rooms roaster. There ring is covered roaster furnace. Wherein the device comprises a gas burner combustion rack, connected hoods (exhaust frame) and the temperature and pressure testing, gas automatic adjustment, metering and other equipment. Each oven chamber has four burners, combustion devices and a set of automatic control system.

2. Control Method

Use the estimated optimization control system--RMPO

3. Systems running the technical requirements

Unit 10 running simultaneously, each combustion cycle system: 20 to 48 hours, roaster gas temperature inside: 900℃, the final products in the baking temperature: 900℃, up to 1280℃.

4. Gas Characteristics

     Hot Thermocouple and temperature change equipment Number of units: 51 units / sets.

4. Control Systems

Requirements of the 2 level control system of the central and field. Composed by a central computer control system basic functions including display, setup, control, storage (year of data), data processing and alarm. The control system composed by the thermostat and the PLC includes on-site display, adjustment, detection, alarm and so on. When the central control system failure, site control systems can set parameters to maintain production.
