Hongxing is always Concentrate On Technology Progress of Rotary Kiln
Our
company mainly produce rotary kiln for ore dressing,30 years of industry
experience to create top quality, Our rotary kiln equipment is trusted by many
customers at home and abroad.What should spare Rotary Kiln welding work
before?
1.The rotary kiln shell welding work must be qualified in the rotary
kiln shell is looking after, and the use of welding gear rotary
kiln.
2.Electrode selection: rotary kiln electrode welds to ensure its
quality should not be less than the mechanical properties of the base metal
mechanical properties, welding process parameters and the specific
implementation requirements of the drawings. Drawing no requirements, must
develop welding instructions.
3.To participate in the rotary kiln shell
welding welder, must pass the examination are allowed to officially participate
in the rotary kiln shell welding. Normally two test panels of each welder
welding, bending and tensile strength required to intercept test specimens for
bending and tensile strength tests. Test panels of material, groove forms,
welding processes are the same requirements and formal welding.
4.Used for
rotary kiln shell welding electrodes, must be dried before use, in the dry box,
the temperature of 250 ~ 300 ℃, drying time is 1 ~ 2h. Dried down to about 150 ℃
temperature preservation, on the insulation tube, used with the check, to avoid
staying too long in the air.
5.Before the deal rotary kiln cylinder welding
groove in the form, size check, not a groove at the delamination crack, slag and
other defects affecting the quality, welded joints before welding on both sides
should be 30 ~ 50mm wide paint , rust and other dirt cleaned, exposing metallic
luster to start welding.
6.Prior to welding, the rotary kiln gear lubricating
roller bearings, roller wipe the surface of debris, with the auxiliary drive
slowly turn rotary kiln shell, the welding ground shall not be connected to the
rotary kiln tire or wheel on the cable insulation measures should be reliable,
have good low welding location lighting, ventilation and insulation. Also, the
rotary kiln in welding workers and establish communication links between
operators.With its high quality products such as 、、Henan Hongxing mining machinery Co.Ltd has ascended in the front rank
of the world in the exporting of mining equipments.
