Tug kiln - kiln bauxite - Henan Kang million Machinery V0322 Phone: 0371-69598888 0371-69598666 (Miss Kang) kiln hood, hood kiln production, installation, repair techniques Rotary kiln hood is supporting parts, whose role is to gather in clinker production run temperature to prevent spillover of clinker, and the role of the exhaust fan and the smoke from the cooler to the hot air through the kiln hood into the kiln, to make full use of waste heat, reduce heat consumption purposes. Kiln hood also has a role in collecting and fumes through the kiln. Therefore, kiln hood, hood kiln production quality, installation quality is good or bad, can play its due role in the production of rotary kiln and heat consumption has a direct impact. A kiln hood, under the hood kiln 1. plates and steel production before feeding, straightening and leveling must be allowed to use a slow arc and undulating steel plates and variant. 2. The sheet metal to allow splicing plate must fight again after leveling press, the plane of the plate of 1 mm / m. 3. The next board material, good looking after strict vertical lines, diagonal to the following correction must measure the geometry of the material. Diagonal deviation should be controlled at ± 0.2 mm / m. 4. When assembled, the sample must be assembled to enlarge as a benchmark, a large sample of diagonal deviation should be controlled at ± 0.2 mm / m. 5. The assembly components should be implemented on the platform, so that both parts to ensure accurate amplification can prevent the kind of testimony was uneven surface can not be combined together to produce equipment installed or defective. 6. The assembly should strictly follow the chassis - housing - such as reinforcing ribs process sequence. Connection for spot welding assembly forms a supporting position, ensure the integrity and geometry, to prevent welding variant. 7. In order to prevent or reduce the welding deformation, should take the first vertical seam welding, after welding seam flat, symmetrical weld welding process. Weld seam quality to meet the design requirements and quality standards. 8. Kiln key cast casing is made of curved plates rolled round and find its cylinder is 1 mm / m 9. kiln hood Ministry and lower casings connection There are basically two forms: one are: upper and lower case by direct butt plate. For ease of installation, welding and weld quality assurance, lower housing without groove on the seams, the upper plate of the housing opening 50 ° ± 2 ° bevel on one side, and leave 3 mm blunt edges. 10. After the lower shell system, marked on the chassis centerline good aspect to look for when you install the positive positioning. Second, the kiln hood, kiln hood to the longitudinal centerline of the installation 1. Roller base as a benchmark to identify kiln hood, kiln hood mounted longitudinal centerline. 2. According to design requirements, to the lateral centerline idler gear 1 as a reference base, identify the kiln hood mounted transverse centerline. To the end of the transverse centerline gear Roller kiln base as a benchmark to identify the transverse centerline kiln hood installation. 3. According to the design requirements to a level base for the idler gear benchmark calculation to find out the kiln hood installation elevation. To the end of the idler gear base elevation as a benchmark to calculate and identify the installation elevation kiln hood. 4. identify and determine the site of vertical, horizontal centerline elevation based on complete control the lower body on the chassis indicate the vertical and horizontal centerline, hoisting. 5. The lower casing installation must find a good level with the level of foot, the flatness of 1 mm / m. 6. The contact surface casing and concrete structures must be flat, solid, if necessary, wipe the surface with mortar. Alignment used horn, wedges, after the completion of the alignment must weld.
