1 General Provisions
1.0.1 This Code is formulated to improve the installation engineering quality of heavy non-
ferrous metal metallurgy equipment, ensure the safe operation of heavy non-ferrous metal
metallurgy equipment, and promote the advancement of equipment installation technology.
1.0.2 This Code is applicable to the construction of installation engineering of
pyrometallurgical equipment, hydrometallurgical equipment, and dust collection equipment in
heavy non-ferrous metal metallurgy.
1.0.3 The materials, specifications, and models of the materials, equipment, and components
used in the engineering must meet the design requirements; and their quality shall comply with
the provisions of the relevant national or industry standards; and they shall be provided with
exit-factory certificates, quality certification documents, and material certificates.
1.0.4 In addition to complying with the provisions of this Code, the construction of installation
engineering of heavy non-ferrous metal metallurgy equipment shall also comply with the
provisions of the current relevant national standards.
4 Pyrometallurgical Equipment
4.1 General requirement
4.1.1 This Clause applies to the installation engineering of heavy non-ferrous metal
pyrometallurgical equipment. The installation of heavy non-ferrous metal pyrometallurgical
equipment shall be constructed in accordance with this Code.
4.1.2 Before installing heavy furnaces and kilns, permanent center label plates for the
longitudinal and transverse foundation center lines must be set. Four settlement observation
points and elevation reference points are set around the foundation of the supporting roller
device.
4.1.3 Before installing the water-cooled components of the pyrometallurgical furnace, a water
pressure test shall be carried out. The water pressure test shall be carried out in accordance with
the provisions of the design technical documents. If there is no provision in the design, the test
pressure shall be 1.25 times the working pressure; and the pressure shall be maintained at the
test pressure for 10 min; and then the test pressure shall be reduced to the working pressure,
and the pressure shall be stopped for 30 min. It is qualified if the pressure does not drop and
there is no leakage.
4.1.4 All parts of the pyrometallurgical furnace oxygen lance that come into contact with
oxygen or oxygen enrichment must be degreased.
4.2 Steam dryer
4.2.1 The installation of the supporting roller base shall comply with the following provisions:
1 The allowable deviation of the longitudinal and transverse centerlines of each group of
bases is 0.5mm.
2 The allowable deviation of the center elevation of each group of bases is ±0.5mm.
3 The allowable deviation of the horizontality of the transverse centerline of each group of
bases is 0.1/1000.
4 The allowable deviation of the span of each group of bases is ±0.5mm.
5 The allowable deviation of the relative difference of the span diagonal is 1mm.
6 The allowable deviation of the inclination of the longitudinal centerline of the base is
0.1/1000.
7 The adjustment screw shall rotate flexibly, the supporting roller bearing shall be adjusted
freely, and the positioning block shall be fixed in the correct position.
4.2.2 The installation of the supporting roller device shall comply with the following provisions:
1 The allowable deviation of the top elevation of the roller device is ±0.5mm.
2 The allowable deviation of the distance between the centerlines of the base is ±0.5mm.
3 The allowable deviation of the inclination of the top surface of the supporting roller is
0.1/1000.
4.2.3 The installation of the cylinder shall comply with the following provisions:
1 The radial clearance between the rolling ring and the cylinder pad, and the clearance
between the rolling ring and the head plate shall comply with the design requirements.
2 The relative position of the rolling ring width center and the supporting roller width center
shall comply with the design requirements.
3 The contact length between the rolling ring and the supporting roller shall be no less than
60% of the rolling ring.
4 The allowable deviation of the spacing between the gear ring and the rolling ring is ±1mm.
5 The allowable deviation of the radial runout of the rolling ring is 1mm.
6 The allowable deviation of the radial and end runout of the gear ring is 1mm.
4.2.4 The assembly of the gear ring shall comply with the following provisions:
1 The joint condition of the gear ring and the tooth pitch deviation shall comply with the
provisions of the technical documents. If there is no provision, the gap at the joint of the
spliced gear ring shall be no greater than 0.1mm; and the allowable deviation of the tooth
pitch is ±0.005 module.
2 The arc and curvature of the spring plate connecting the cylinder, and the fit of the arc
surface with the cylinder shall meet the design requirements.

requirements:
1 The relative position of the centerline of the large gear ring and the small gear shall meet
the design requirements, and the bolts shall be tightened.
2 The engagement contact surface and engagement clearance between the gear ring and the
small gear shall be adjusted based on the large gear ring. The contact area between the
large and small gears shall be no less than 40% tooth height and 50% tooth width; and
3 The allowable deviation of the verticality is 2/1000.
4.3.3 The installation of the grate bar shall comply with the following provisions:
1 The allowable deviation of the center distance of adjacent grate bars is ±3mm.
